Abstract

Se divulga un procedimiento para la produccion de un producto de plomo blando purificado, que comprende a) una primera etapa (200) de destilacion para destilar plomo a partir de una mezcla (6) de soldadura fundida para producir como parte superior una primera corriente (7) de plomo concentrada y como primer producto (8) de la parte inferior una mezcla de estano crudo fundido, y 10 b) una etapa (700) de refinacion de plomo blando para eliminar al menos un contaminante seleccionado de arsenico, estano y/o antimonio desde la primera corriente de plomo concentrada al tratar la corriente a una temperatura de menos de 600°C con una primera base (24) y un primer oxidante (25) mas fuerte que el aire, lo que resulta en la formacion de una tercera espuma (26) sobrenadante que contiene un compuesto de metalato del contaminante, seguido por la separacion de la tercera espuma (26) sobrenadante de la corriente de plomo blando purificado o producto (27), por lo cual la tercera espuma (26) sobrenadante de la etapa (b) contiene a lo sumo 1,0 % en peso de cloro.A process for the production of a purified soft lead product is disclosed, comprising a) a first distillation stage (200) for distilling lead from a molten solder mixture (6) to produce as top a first stream ( 7) concentrated lead and as a first bottom product (8) a mixture of molten crude tin, and 10 b) a soft lead refining step (700) to remove at least one contaminant selected from arsenic, tin and/or or antimony from the first concentrated lead stream by treating the stream at a temperature of less than 600°C with a first base (24) and a first oxidant (25) stronger than air, resulting in the formation of a third foam (26) supernatant containing a metalate compound of the contaminant, followed by separation of the third foam (26) supernatant from the stream of purified soft lead or product (27), whereby the third foam (26) supernatant e from step (b) contains at most 1.0% by weight of chlorine.
